Chemical Structure
Description
As a certified reference material (CRM), 2-(difluoromethyl)furan-3-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 2-(difluoromethyl)furan-3-carboxylic acid (CAS 1655558-07-8), a certified reference material (molecular formula C6H8F2O3, MW 166.12 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(difluoromethyl)furan-3-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
